[A case of recurrent breast cancer with carcinoma erysipeloides responding to sequential therapy with docetaxel (TXT) and doxifluridine (5'-DFUR) accompanied by leucovorin (LV)].

A left radical mastectomy was performed on a 53-year-old woman, diagnosed with left inflammatory breast cancer, after local arterial chemotherapy with cyclophosphamide (CPA), doxorubicin and 5-fluorouracil (5-FU). Adjuvant therapy was added with irradiation and ECF. Four months after the operation, a red eruption was detected on the left upper chest wall. The lesion was diagnosed by skin biopsy as a recurrent breast cancer with carcinoma erysipeloides. Tumor marker levels suggested the recurrent cancer was ECF resistant, so we changed the chemotherapy regime to a single dose of TXT. Although tumor marker levels and the skin eruptions improved at the beginning of the therapy, pleuritis carcinomatosa was found. We changed the regime again to a continuous dose of 5'-DFUR and LV for day 1 to 7. With this regime the clinical symptoms improved, and 2 courses of this modified FL therapy were carried out. After the therapy, the tumor seemed resistant to this modified FL therapy. Therefore, we tried a sequential therapy with TXT and the modified FL, which induced an improvement in clinical symptoms. Two years later, the patient died from the breast cancer. Therefore, we conclude that the sequential therapy may be beneficial in managing untreatable carcinoma erysipeloides of recurrent breast cancer.
